Voltage Drop Detection for Output Power Supply
This section describes the voltage drop detection for output power supply.
Overview and Applications
This function monitors the output power supply voltage fed to the Digital I/O Variable Hub, and detects
voltage drop when the voltage decreases below the monitored voltage.
Applicable Hubs
Digital I/O Variable Hub
Function Details
This function detects voltage drop when the voltage is certainly below the lower limit for the output
power supply. You cannot configure the monitored voltage.

How the Power Supply Voltage Drop Detection Works
If the function detects power supply voltage drop, the following bits of process input data turn ON
and the
Output Power Supply Voltage Drop (8CB0 hex) device event occurs.
Refer to Process Input Data of the Digital I/O Variable Hub in 6-1 Process Data on page 6-2 for
details on the process input data.

Output Power Supply Voltage Drop Detection Bit
*1
•
Output Power Supply Voltage Drop Detection Hold Bit
*1. When this status is TRUE, the Output Data of the process data is invalid. Use the Output Data when the
status is FALSE.
The Output Power Supply Voltage Drop Detection Bit turns OFF when the cause of the power sup-
ply voltage drop is removed.
